-
-## Configuration for Build
-
-### Enable Network Resilience Features
-Create or update your `config.toml`:
-```toml
-[server]
-listen_address = ":8080"
-enable_dynamic_workers = true    # Enable dynamic scaling
-worker_scale_up_thresh = 50      # Scale up threshold
-worker_scale_down_thresh = 10    # Scale down threshold
-deduplication_enabled = true     # Enable deduplication
-max_upload_size = "10GB"         # Support large files
-
-[uploads]
-chunked_uploads_enabled = true   # Enable chunked uploads
-resumable_uploads_enabled = true # Enable resumable uploads
-chunk_size = "10MB"              # Optimal chunk size
-max_resumable_age = "48h"        # Session persistence
-
-[timeouts]
-readtimeout = "4800s"            # 80 minutes for large files
-writetimeout = "4800s"           # 80 minutes for large files  
-idletimeout = "4800s"            # 80 minutes for large files
-
-[deduplication]
-enabled = true
-maxsize = "1GB"                  # Deduplicate files under 1GB
-
-[security]
-secret = "your-super-secret-hmac-key-minimum-64-characters-recommended"
-```
-
-## Testing the Build
-
-### 1. Basic Functionality Test
-```bash
-# Test binary works
-./hmac-file-server --help
-
-# Test with config file
-./hmac-file-server --config config.toml
-```
-
-### 2. Test Network Resilience Features
-```bash
-# Start server with chunked uploads enabled
-./hmac-file-server --config config.toml
-
-# In another terminal, test chunked upload endpoint
-curl -X POST \
-  -H "X-Filename: test.txt" \
-  -H "X-Total-Size: 1024" \
-  -H "X-Signature: $(echo -n '/upload/chunked' | openssl dgst -sha256 -hmac 'your-secret' | cut -d' ' -f2)" \
-  http://localhost:8080/upload/chunked
-```
-
-### 3. Run Go Tests
-```bash
-# Run existing tests
-go test ./test/...
-
-# Run with verbose output
-go test -v ./test/...
-
-# Run specific tests
-go test -run TestUpload ./test/
-```
-
-## Docker Build (Alternative)
-
-### Using Existing Docker Setup
-```bash
-# Build Docker image
-./builddocker.sh
-
-# Or manually
-docker build -t hmac-file-server .
-```
-
-### Run with Docker
-```bash
-# Start with docker-compose
-cd dockerenv
-docker-compose up -d
-
-# Or run directly
-docker run -d \
-  -p 8080:8080 \
-  -p 9090:9090 \
-  -v $(pwd)/config:/etc/hmac-file-server \
-  -v $(pwd)/data:/var/lib/hmac-file-server \
-  hmac-file-server
-```
-
-## Troubleshooting
-
-### Build Issues
-
-#### Missing Dependencies
-```bash
-# Clean module cache and re-download
-go clean -modcache
-go mod download
-```
-
-#### Go Version Issues
-```bash
-# Check Go version
-go version
-
-# Update Go if needed (Ubuntu/Debian)
-sudo snap install go --classic
-
-# Or download from https://golang.org/dl/
-```
-
-#### Network Resilience Files Missing
-```bash
-# Check if files exist
-ls -la cmd/server/upload_session.go
-ls -la cmd/server/network_resilience.go
-ls -la cmd/server/chunked_upload_handler.go
-ls -la cmd/server/integration.go
-
-# If missing, the build will work but without network resilience features
-# Core functionality remains unchanged
-```
-
-### Runtime Issues
-
-#### Port Already in Use
-```bash
-# Check what's using port 8080
-sudo netstat -tlnp | grep :8080
-
-# Kill process if needed
-sudo kill $(sudo lsof -t -i:8080)
-```
-
-#### Permission Issues
-```bash
-# Make binary executable
-chmod +x hmac-file-server
-
-# For system service installation
-sudo chown root:root hmac-file-server
-sudo chmod 755 hmac-file-server
-```
-
-#### Config File Issues
-```bash
-# Validate config syntax
-./hmac-file-server --config config.toml --validate
-
-# Use example config as starting point
-cp config-example-xmpp.toml config.toml
-```
-
-## Build Performance
-
-### Faster Builds
-```bash
-# Use build cache
-export GOCACHE=$(go env GOCACHE)
-
-# Parallel builds
-go build -p 4 cmd/server/*.go
-
-# Skip tests during development
-go build -a cmd/server/*.go
-```
-
-### Smaller Binaries
-```bash
-# Strip debug info and symbol table
-go build -ldflags="-s -w" cmd/server/*.go
-
-# Use UPX compression (if installed)
-upx --best hmac-file-server
-```
-
-## Deployment
-
-### System Service
-```bash
-# Copy binary to system location
-sudo cp hmac-file-server /usr/local/bin/
-
-# Create systemd service
-sudo cp hmac-file-server.service /etc/systemd/system/
-sudo systemctl enable hmac-file-server
-sudo systemctl start hmac-file-server
-```
-
-### Reverse Proxy Setup
-```bash
-# Nginx configuration
-sudo cp nginx-hmac-file-server.conf /etc/nginx/sites-available/
-sudo ln -s /etc/nginx/sites-available/hmac-file-server.conf /etc/nginx/sites-enabled/
-sudo nginx -t && sudo systemctl reload nginx
-```
-
-This build process ensures that:
-- ✅ **Backward Compatibility**: Works with or without network resilience files
-- ✅ **Feature Detection**: Automatically includes available network resilience features  
-- ✅ **Zero Downtime**: Existing deployments continue working unchanged
-- ✅ **Mobile Optimized**: New features specifically address network switching issues
